Working 2.0.0 build for Windows

It is really late so I'm calling it here. I wanted to put this out for relevant people to get eyes on, in order to aid in getting the Windows build of v2.0.0 out. Apologies in advance for not following any contrib guidelines or there being messes.  I'm leaving in the build scripts I used for now. The build scripts still contain a few hardcoded visual studio related values for now.  At the moment when I run the app on a different machine to the dev VM I'm using the qt web view doesn't seem to be rendering.

summary of where this is at:
the whole thing builds
works on my Windows 11 virtual machine

short summary of what I did:

A couple of qt6 updates specific to windows were addressed.

Some build system issues were addressed

did some minor refactoring to sieve out binary build dependencies from generated build files since its a lot easier when you can just delete the build folder to run a clean build
